62 THE CANADIAN ENTOMOLOGIST, 



The Colorado species is Freya. The examples taken bj' Mr. Mead in 

 Colorado, 187 1, and of which Mr. Scudder speaks, all passed through my 

 hands, as did the whole catch, i received the butterflies, week by week, 

 through the mails in papers ; and, on Mr. Mead's return, we divided the 

 entire lot equally between us. There were many Freya (and some of 

 them I have now), but no Chariclea ; nor has CJiariclea ever been taken 

 within the limits of the United States, so far as I know. It flies as far to 

 the south as the Canadian Pacitic Railway in the Rockies ; and I not only 

 have examples taken at Laggan by Mr. Bean, but I have twice had eggs 

 and larvae from him.* 



II. On p. 1863, in the synonymy of Pamphila (Limochoies) Palaika 

 it is said that Pamphila Dion Edw., Can. Ent., XL, 238, is the same thing. 



*Mr. Scudder says, page 1807, under Freya, by which he means Chariclea : "To 

 judge from the captures north of Lake Superior, it is a late species, flying late in August 

 and early in September, or at the very close of the season, at that place. Evidently 

 winter must be passed, by the caterpillar just from the egg." I have not learned from 

 Mr. Bean the date of first appearance of Chariclea imago, but I received eggs sent by 

 him 4lh of August, 1866, and another lot 6th August, same year. Part of each lot hiber- 

 nated direct from the egg, but part went jiast third moult and then hibernated. I lost 

 these during the winter. But these last larvre, had they lived, would have reached 

 imago three or four weeks earlier than the larva? that hibernated from the egg. This 

 would give the appearance of two broods of the butterfly, and account for some flying in 

 July and others in September. 



Under Cliariclea, p. 1809, by which Mr. Scudder means Freya, we read : " Noth- 

 ing is known of its seasons or history, except that it appears in Colorado early in the 

 season, in May, or early in June, so that winter can certainly not be passed as a cater- 

 pillar just from the egg." I have not had eggs of Freya from Colorado, but received 

 some from Laggan, sent 6th June, 1886; and again, sent 4th June, 1889. I lost the survivors 

 of the first lot after they had passed the second moult ; but those of the last lot (6) reached 

 eight-tenths of an inch in length, and had passed three moults before 2nd July. I 

 thought from their actions they would pupate, but after several alternations of quiet and 

 activity, they finally dropped asleep, and I sent them to Clifton Springs, N. V., i6th of 

 July, to go in the refrigerating house. 



The species A. Helena is the representative of Chariclea in Colorado, and as that 

 behaves so Chariclea might be supposed to behave, if it dwelt in Colorado. Eggs of 

 Helena, sent from that State 24th July, 1886, gave larv;\:. all of which passed the third 

 moult and then went into hibernation. I lost them during the winter. 



I may as well here speak of one other of this group, A. Triclaris, found in Colo- 

 rado and north. I received eggs sent from Laggan, 2nd August, 18S9. The larvee 

 passed second mriult and hibernated, and were sent to Clifton Spiings 19th September. 



The larvK of all four species are closely like that oi Belloiia. In the first stage, the 

 alternate segments are green and brown, as in Bellona, and also Myrina. The spines 

 of Triclaris are somewhat different from the rest after the first stage, but these others are 

 same as in Bellona, so far as I carried the larva:. Mr. Scudder has tried hard to find 

 characters in the preparatory stages by which to separate the genus Brenthis Scudder 

 (not the coitus Brenthis of Hubner, by a good deal), but wholly without success ; and 

 the same is true of the imago. The small species are merely a group of the genus 

 Argynnis. As to two other genera, so called, chipped off from Argynnis, viz., Semno- 

 psyche and Speyeria, there is not a feature in any stage to justify either of them,
